20120199084 | THERMOSTAT AND COOLING DEVICE FOR VEHICLE - If an engine undergoes high-load operations immediately after start up from its cold state, a thermostat is closed to inhibit passage of cooling water through the inside of the engine, and the cooling water stagnant in a cylinder head receives heat from a combustion chamber.
